She has been living with her master in Baifu since Bai Ruoer can remember. The master treated her like his own daughter. He taught her the Four Books and Five Classics, taught her how to practice the sword and play the piano, taught her how to practice medicine and heal wounds... But he did not teach her to recognize the human heart. Bai Yuan thought that Bai Ruo'er would stay with him for eternity and eternity in this Bai Mansion. He thought that there would always be a chance to express his feelings when she was older. But things always happen so unexpectedly. Bai Yuan, even with all his hands and eyes, can't stop Bai Ruo'er, who has just begun to fall in love, from falling in love with a man who makes her fall into hell. Bai Ruo'er from Xue Chen's house was dressed in red and was about to get married, "You can only choose one between me as a teacher!" Bai Yuan forced her. He believed that he would not be wrong about her since he was a child, and she would definitely choose him. Even if there is only a shell left by his side from now on, he will keep her. Bai Yuan smiled bitterly, when did he, Bai Yuan, want something and someone want to use this method to stay? "Forget it, I won't force you, just let him go. From now on, I will pretend that I don't have you as my disciple." Bai Ruo'er cried all over her bridal makeup and knelt down to thank her master for raising and teaching her. Bai Yuan left without looking back... Eight years later, Bai Yuan looked at Bai Ruo'er who had fainted due to excessive blood loss on the ground and was filled with anger. He had raised this disciple since he was a child and never let her hurt a single hair. Now, he was hurt like this, and the culprit was actually the man that the weakling cared about most - Xue Chen. Bai Yuan picked up Bai Ruo'er who was only breathing: Ruo'er misjudged the wrong person, this is her price, and you, Xue Chen, you hurt my disciple, your price, I will pay you back slowly...
